This invention relates to oil separators 'suchas are used in connection with steam driven machinery to remove lubricating oil from the exhaust steam for" the purpose both ofsavingthe oil and of purifying the steam so that wh'en condensed it mayv be suitable fon-u's eagain in the boiler Or for other pur poses.. The invention consists in the struc-= tural features "and-arrangement oi? parts in thevac companying drawings herein Flg. 1-1s a s'ectlonal PBISPGCUVG' View of one"-iorin of the invention to be employed when theexhaust steam pipe extends verti cally. Y I 'Figurefl is a sectional detail showing a being taken on line 2-2 of Figure 1.

Figure 3 is a similar View showing the construction preferred in conjunction with a horizontal exhaust steam pipe.

In these views the reference character A designates the cylindrical main casing of the oil separator and B and C are respectively exhaust steam inlet and outlet pipes axially communicating with the casing A at the bottom and top thereof. Centrally within the casing A there is'disposed a cylindrical shell D within which is formed a steam expansion chamber, said shell being in communication with the inlet pipe B through a short extension E of the latter. To the top of said shell I The exhaustv capes downwardly through -short' opening into the shell 4 through the bottom thereof. Said pipes pro'ject'slightlyfat their I.

lower end into concentric cups Got alarger diameter which are secured by any suitable means to the 'floo'r of the casingA. Adja- 'cent said floor the cups G are'each formed with a plurality ofoutlets G j for -the oiland con densation. ,The pipes F form also outlets! 1 tromthe shell D for the purified exhaust steam which tlows through saidp'ifpes-ijnto the cups Gr and reverse its directionkoftrayel within said clips; into the main casingA between' said cups and the pipes -Fii :This reversal in the direction o'fj the" flow of steam exerts a fur-thertendenoy'toremove from said steam any oil that -may still be carried in suspension'and spiral bafiilememe has H respectively interiorIy securedito the;

cups G contribute to the same result.

further I expansion of VI the steam occurring with-in the space :between: the :shellrfD and main casingiA exercises a still turther tend- .enc'y to precipitateanyEsuspendedoil. wI'naddition :to the lmain exhaustisteamxoiitlet C there are provided auxiliary outlets which may lead to any apparatus in which it is desired to utilize a portion ofthe purified steam. Thus Figure 1 shows outlets H and H opening into the casing A respectively,

through the top and side of the latter.

It is preferred to arrange a vertical baflle plate J in opposed relation to the horizontal outlet H, said plate having atits verti cal edges flanges J whereby the plate is adapted to be-riveted'or otherwise secured to the side wall of the casing A in spaced relation to the shell D and outlet H. Thus any steam reaching said outlet is compelled to undergo a number of reversals in its direction oi travel which tends to throw out any oil still in suspension. Ports J formed in said plate at its lower edge prevents any trapping of condensation by said plate. 1

indicates a pipe having a discharge connec tion with the casing A throu h the. bottom.

the separated j thereof and serving to carry 0 Oll together with any water resulting from steam condensation. There may occur within the extension E a small condensation ofsteam or deposit of oil and provision is made ifordischarge of the same by way of a horizontal pipe K extending within the casing A adjacent the floor thereof from the said' extension to the discharge pipe K. L is pipe laterally entering thecasing A and having a T-head L for discharging live steam at low velocitywithin said casing exjteriorly of; the shell D. The live steam thus introduced will serve to maintain the'steam pressure necessary for such apparatus as may be served by the auxiliary outlets H and H. The head L directing the live steam laterally against the curved side face of the casing secures a deflection of the steam from the; surface impinged upon without detrimental-result to said surface. -M is aivae-uum breaker communicating through the fcasingA withthe shell D.

In" the form of theinvention illustrated in, Figure 3, the exhaust steam inlet and outletpipes 13 and ,C arerin horizontal communication, with the'casing A the lat- .t'erbeing arranged coaxially with said pipes and having all of the interior parts correspondingly-arranged. Otherwise the construction, substantiallyduplicates I that first described except that a drain pipe 0 is connected withthe bottom of the. shell D toprevent any accumulation of oil orzwater of condensation in said shell. I

, It is to be understood that the described oilseparator may be used either independently, as illustrated, or may be combined with 'afeed water heater or with a water heater or steam purifier of any sort. VVhatIclaimas my invention is 1. In an oil separator, a casinghaving an exhaust steam inlet and 0utlet,and oilsep arating'means within said casing, said casing having a ,cylindricalwall and a live steam pipe entering said casing? and having a head within the casingdischarging at. an acute angle against said wall ,whereb the curved surface [of 'said wall deflects the steam without detrimental effect upon said wa l.

2. In an oilseparator, the combination with the casing thereof, said casing having an inlet and outlet for exhaust steam, otan oil-separatingchamber within said casing between said inlet and outlet, steam and. oil discharge passages from: said chamber into said casing,an oil'drain pipe open-inginto the bottom of said casing, a passage connecting the exhaust steam inlet with said chamher and a drain pipe connectin said passage with the drain opening into t e bottomot the casing. 3. An oil separator comprising a easing having a plurality ofrexhaust 'steam'o-utlets, a shell arranged centrally within andhav ing an outlet to said casing, means tor delivering exhaust-steam to said shell, baffles encountered by the steam: infdischarging from the shell to. the'casing, and: means for delivering live steam to said casingmw. 4c. In an oil separatonmthe combination with the casing thereof, said casinghaving an inlet and mainand auxiliary outlets for exhaust steam, of an oil, separating chamber within said casing between said inlet and the main outlet, and, abatfie plate disposed within said casing between the oil separating chamber and the auxiliary :outlet in proximity toithe latter. i 1 1 In testimony whereof I affix my signature.
